Safety information
Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
Ensure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.
